my blog is not connected to my user profile - no primary blog

just created a new account - the blog got created and I am also able to log in at wordpress.com, but my blog does neither appear at the list of blogs ("Your blogs:" at the front page), nor in "Edit Profile->Primary Blog" (there I see: "Primary Blog: wordpress.com", nothing selectable). Anything I can do? I can't even delete my blog nowhere, and I don't want to do this anyway since I would like to keep the blog address/name...
